 Currently QGIS has two different methods for editing:
 - one (optionally) pseudotopological, to be used with SimpleFeature layers
 (shp, postgis, spatialite etc.)
 - one fully topological, limited to GRASS layers.
 IMHO it would be good to unify the two, digitizing always (optionally?)
 with full topology, and writing (a)topologically when on a topological
 format (in future also e.g. GML3-topo, PostGIS-topo), (b) non
 topologically when on SF.
 This would be both more powerful and clean, and less confusing for users.

 (topological) features.
